French biotechnology firm Carbios has announced the signing of a multi-year commercial agreement with Thai integrated chemical firm Indorama Ventures. This agreement covers the supply of biorecycled monomers from its Longlaville plant, which will be transformed into r-PET filaments by Indorama and then integrated by French tyre maker Michelin into the manufacturing of its tyres.
Thanks to its enzymatic PET recycling technology, Carbios will produce monomers from complex PET waste at its future industrial site in Longlaville. Indorama will handle the repolymerisation and production of technical filaments. Michelin will use these materials in its tyre reinforcements.
This commercial agreement is part of the pre-commercialisation momentum of Carbios’s future industrial site in Longlaville, just weeks after signing the first sales contracts for biorecycled PET with global cosmetics leaders, L’ORÉAL and L’Occitane en Provence.
Vincent Kamel, CEO of Carbios said, “This commercial agreement with Indorama Ventures marks a new step in the realisation of our industrial project. It confirms the trust of Indorama Ventures and Michelin in our PET biorecycling technology. Alongside the commercial successes already achieved in cosmetic packaging applications, this agreement illustrates our ability to deliver innovative solutions to the most demanding industries, particularly industrial filaments for tire applications and, more broadly, textile.”
Fabien Gaboriaud, Director of Circularity and Renewable & Recycled Materials at Michelin Group, conferred, “This partnership is a tangible expression of our commitment to turning complex waste into high-performance materials. By integrating enzymatically recycled r-PET into our tyres, we are marking a new milestone on our journey toward achieving 100% renewable and recycled materials by 2050 — all while staying within planetary boundaries. It is by combining innovation, industrial excellence, and close collaboration with trusted partners that we are building a strong and lasting circular model.”
Carbios’s industrial demonstration plant for biorecycling has been operational since 2021, and construction of the world’s first biorecycling plant is expected to resume in the second half of 2025, subject to securing the necessary additional funding.
The company is supported by prestigious brands in the cosmetics, food, and apparel industries, aiming to improve the recyclability and circularity of their products. Nestlé Waters, PepsiCo, and Suntory Beverage & Food Europe are members of a packaging consortium founded by Carbios and L’Oréal. On, Patagonia, Puma, PVH Corp and Salomon collaborate with Carbios in a textile consortium.
